Manufacturing Quality Control of 4,4'-Diaminobenzanilide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to combust organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Reaction with ammonium sulfide under controlled pH to form colored metal sulfide complexes, compared visually or spectrophotometrically. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential jump due to AgCl precipitation. |
| Sulfated Ash | Gravimetric Analysis | Sample charred, treated with sulfuric acid, ignited at 600-700 C, and residual sulfate ash weighed. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary tube apparatus per USP <741>. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of volatile impurities using capillary GC column and flame ionization detection. |
| Related Substances | HPLC-DAD | Separation by reversed-phase HPLC with diode array detection to identify and quantify structurally related degradation products and synthesis intermediates. |
| Iron Content | Atomic Absorption Spectroscopy (AAS) | Quantification of Fe via absorption of specific wavelength light (248.3 nm) by ground-state atoms in acetylene-air flame. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measurement of hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to determine volume-based particle size distribution in dispersed slurry. |
